MACHINE FOR MAKING METALLIC ROOFING SPECIFICATION forming part of Letters Patent No. 365,540, dated June 28, 1887.

Application filed December 24, 188d. Serial No. 222,452. (No model.) I

To all whom it may concern:

Be it known that I, LONGLEY Lewis SAGEN- DORPH, a resident of Cincinnati, Hamilton.

Metallic Roofing, of which the following is a specification.

The principal feature of the invention herein described consistsin the additionto and combination with the machine described 'inUnited States Letters Patent No. 306,645, granted to me October. 14, 1884, of a novel device for, cutting cleats in the crimped sheet of roofing, and also in a new devicefor preventing buckling r 5 of the sheet whilebeing crimped.

In the accompanying drawings, forming part of this specification, Figure 1 is a front elevation of a machine embodying my invention, with this exception, that the springs atthe back of the machine for assisting in elevating the bar I, and which would be partially seen from the front, are omitted, as their presence would tend to confuse the presentation of these portions of the machine which are in front.

Fig. 2 is a rear elevation of the machine, the

eccentrics which operate the dies being omitted. Fig. 3 is an end elevation of that end of the machine which is at the right hand in Fig.

1, the fly-wheel and crank being omitted to enable important mechanism to be seen. In this figure the male dies are shownat their highest points of elevation. Fig. 4 is a transverse vertical section taken at the line a: of Fig. 1 and looking'toward the left hand, the spring L, for assisting in elevating the bar I, being omitted to prevent confusion in showing other parts. shown seated. From all of the foregoing figures the legs on which the machine is mounted are omitted. Fig. 5 is an enlarged view of the preferred description of cutter for cutting the diagonal slits. Fig. 6 is an enlarged view of the cutter whereby the cleats are cut in the sheet. Fig. 7 represents in perspective a portion of the length of a metal sheet which has been crimped andcut by my machine, that side of the sheetbcing uppermost which is beneath when the sheet is in the machine and being operated upon. Fig. 8 is a section taken at the line :0 a: of Fig. 1, corresponding to Fig. 4, but showing the dies and operating In this figure both male dies are mechanism in the position shown in Fig. 3. Fig. 9 is a section similar to Fig. 8, but showing the eccentric very near to one end of its throw, one die being seated and the other die 5 slightly elevated. Fig. 10 is aside view of one of the devices for operating the clampingboard. Fig. 11 illustrates in vertical crosssection some of the forms in which the edge portions of a metallic sheet may be crimped 6 by my machine. Fig. 12 is an enlarged end view showing the bed-plate, a small portion of the frame, the female dies, and a portion of the male dies in their relative positions, the male dies being raised. The legs or equivalent supports upon which the main or body portion of my machine rests may be of any suitable form.

' The various parts of the frame-work of the machine are indicated by the-letter A.

At the. sides of the bed-plate B are placed the female or intaglio dies 0. The male or cameo dies D fit in guides cl in the sides of the frame-work, and are suspended from the top of the frame-work by toggle-arms E E. Each 7 5 die is preferably provided with three or four sets of-toggle-arms. The upper toggle-arms are renderedadjustable in length, preferably by the means shown, which consists of forming the arm in three sections, the middle section s being provided with right and left screws, which fit into the end sections. The togglearms for the different male dies are adjusted to unequal lengths. In the'machine shown in the drawings the set of toggle-arms supporting 8 the die farther from the eccentric is adjusted to be the longer. The toggle-arms of the two male dies are united by connecting-bars F. Each bar F is made in two parts, which are united to each other by being screwed into the 0 link F. The screws on the two parts of the rod F being, respectively, right and left hand screws, the length of the whole bar F may be regulated by means of the link F. When the toggle-arms supporting the die farther from the eccentrics are made longer than the set of toggle-arms supporting the nearer die, the bars F are made shorter than the distance between the two dies themselves, and when the nearer toggle-arms are thelonger the bars F are made longer than the distance between the dies.

The main or operating shaft G is journaled in brackets A A projecting from the frame of the machine. It is provided with fly-whecls G and (when operated by hand-power) with a crank or cranks, G to turn it. The shaft is also provided with a series of eccentrics, 9, one being placed opposite each of the sets of toggle-arms E. lhe connectingrods g extend from the straps g of the eccentrics to the toggle-arms E, and impart to these toggle-arms the motion of the eccentrics thereby lowering and raising the male dies.

The male die nearer the eccentric is provided with atooth, d, and the other male die is provided with a tooth, (1 'Each of these teeth extends the whole length of its respective die. The teeth (1 d together with the corresponding parts in the female dies, form, respectively, the ridges E and E of the sheet-rooting. (See Fig. 7.)

\Vhen a slit or slits are to be cut in the sheet, such as indicated by 71 Fig. 7, the male die for forming a crimp in that edge portion of the sheet where the slit is to be cut is provided with a cutter or cutters, H, (see Fig. 3,) one cutter for each slit. Of course, when each edge of the sheet is to be provided with a slit or slits, each male die is to be provided with a cutter or cutters, H, as the case may be.

The cutters H are preferably made separate from the dies D, as shown in Fig. 5, and are secured to their respective dies in any desired manner and set at any desired angle. These cutters make slits in the sheet in any desired direction. In the present illustrative instance they make the diagonal slits h in the sheet.

The bar I is placed behind the rear die, D. It extends from end to end of the machine, is directed by guides z (see Figs. 2 and 3) in the frame-work, and suspended from the top of the frame'by toggle-arms J in the same way as the dies D are suspended. The different sets of toggle-arms supporting the bar I are united by a longitudinal bar, K. This latter bar has a to-and-fro longitudinal movement imparted to it by means of an eccentric, K, the latter being operated by the crank K To partially counterbalance the bar I. and assist in raising it, the springs L are provided, which are attached to the bar and to the frame above. The bar I has attached toit a number of cutters, M, which fit in corresponding reccsses,M-,in the rear die, D, and descend into the recesses M in the die (3. The under surface of each of these cutters M is beveled, as shown in Fig. 6, so that one end projects farther down than the other end. These cutters M are present when cleats, as m, are to be cut in the sheet, substantially as shown in Fig. 7.

The clamping board, plank, or plate N we tends from end to end of the machine, and is suspended by the springs N from the framework. At each end of the clamping-board N, and journaled in bearings 0, attached to the frame-work, is an eccentric, 0, having the lever-arm O, by means of which the eccentric is operated to depress the clampingboard N against the bed-plate B. On the forward female die 0 are placed two or more adjustable steps or guides, I, to determine the location of the sheet of metal in the machine. (See Figs. 1, 4, 8, and 9.) Each guide 1? consists of a bracket, P, attached to the die 0 and supporting a screw-threaded rod, P, which moves the tongue 1) back and forth. (See Fig. 8.)

The mode of operation is as follows: The male dies are first raised, as shown in Figs. 3 and 8, to permit the sheet which is to be crimped to be placed in position on the bed-plate B. The sheet is now placed on the bed-plate with its front edge bearing against the tongues p of the stops P. The eccentrics O are now turned down, depressing the clamping-board N, which holds the sheet of metal more or less firmly in position. The cranks G are now turned, imparting motion to the eccentrics g, which in their turn impart a longitudinal movement to the rods and F, which lower the male dies. )Vith the mechanism adjusted as shown in the drawings that male die which is thenearer to the eccentrics g is first seated, and is seated shortly before the eccentrics reach their full throw. This position of the mechanism is shown in Fig. 9. As the eccentrics continue in their throw, the other die continues to descend, and reaches its seat just as the eccentric completes its throw. )Vhile theoretically the first die is raised by the continuation of the movement of the eccentric, practically it is not, and when the eccentric has reached its full throw the dies are both seated, as shown in Fig. 4:. It is necessary to have the dies seat at different times, in order to prevent the sheet of metal being torn. The clamping-board N acts as a tension. As the first die is seated it forces before it the sheet of metal, drawing the sheet from both directions. The amount that the whole sheet is drawn in this operation is determined by the tension of the clampingboard N and the gage or guides P 12. Besides forming the ridges E E the two descending male dies D, through the agency of the cutters H, cut the diagonal slits h. Vhile the sheet is held down by the dies D the bar I is lowered by means of the crank K. The beveled cutters M on the bar I pass through the sheet into the recesses M of the die 0. In this movement the cutters M form the cleats m 011 the sheet, freeing them on two sides, but leaving them attached to the margin of the sheet, and bending them down, as shown in Fig. 7. The edge portion of the sheet may be crimped into different forms, according as the edge of the sheet is made to project a greater or less distance over and beyond that edge of the front female die which is toward the iongitudinal center of the machine. This amount of projection is regulated by the guides or stops Pp. A few of these different forms into which the edge portion of the sheet may be bent are shown in Fig. 11.

The particular shape of ridge formed in the sheet of course depends upon the shape of the ICC IIS

teeth of the dies. The preferred shape of ridge is that shownin the drawings, where the ridge E is shown with both its sides inclined toward the plane of the plate and joining the general plane of the plate through somewhat marked curves, while the other ridge, E, is made with one of its sides nearly perpendicular to the general plane of the plate, with only a slight curve uniting them, while the other side of this ridge is similar to the sides of the ridge E.

The ridge E is, formed by the die which first descends, and the material which goes to formit is drawn partly from the main body of the sheet and partly from that part of the sheet which lies in front of the groove in the female die. The amount of the slip of the whole sheet is determined by the tension of the clamping-board N. When the second ridge, E is'formed, the sheet of metal as a whole cannot slip, but is held immovably by the first die. It therefore follows that the whole of the ridge E is formed from the metal which covers and projects beyond the groove in the rear female die. To accommodate the slip of the metal, I have provided the groove in this female die with sloping sides and given a marked rounding to its edges. When two sheets are united, the broad ridge E is placed over the narrow ridge E of the adjoining sheet. The straight side of the die enables the ridge E to be made narrower than the other ridge. From the mode of action of the machine already described it is seen that the ridge with the straight face must be made by the first die, because after the first die has descended the sheet of metal as a whole is clamped firmly in position, and the material forming the second ridge is drawn entirely from the free edge of the sheet. Now, if the inner faces of the dies which form this second ridge were not inclined, the sheet would be sheared off at the inner edge of the second ridge, E".

The sheet of roofing as it leaves the machine The cleat m is now turned over the ridge E. and onto the sheet at right angles to the edge of the sheet, andis then bent to conform to the shape of the ridge, either by being replaced in the machine or by the use of a special forming-tool operated by hand. These turned-over cleats form a means for locking the sheets together, as fully set forth in United States Letters Patent No. 355,888, granted to me January 11, A. D. 1887. The slits it serve two purposes. They indicate, roughly, the amount of overlapping of adjacent rows of sheets, as the slits h of one row must always be'covered by the sheets of the adjoining row. In the row of sheets which come at the edge of the roof the slits h are continued to the edge of the sheet, as indicated by dotted lines in Fig. 7. The tongue so formed is turned under the edge of the roof and serves to hold the sheet in place.
